,WITNESSES: INVENTOR l l/v'ZZiam Efierimm a %W/%M9 inoperative positionand will permit delivery of a matrix from its respective channel. Suchmeans consists in the present instance of a cam which in the form shownembodies a sleeve 16 provided with alternately or reversely positionedcam projections 17 and 18, these projections being spaced in alter-'nate relation'with respect to the circumference of the cam. The cam ispinned or otherwise keyed to an actuating shaft 19, this shaft beingmounted in suitable bearings 20 onthe upper side of the magazine and aratchet wheel 21 is fixed to the shaft, this ratchet wheel having teeth22 which correspend in number to the number of cam projections, andthese ratchet teeth are spaced in predetermined frelation to the camprojections,

An actuating arm 23 is turnably mounted on the shaft 19 and it carries aspringpressed pawl 24: which, when the actuating arm is turned in one,direction, ,will engage,

a tooth on theratchet wheel 21 and rotate the latter one step, the cambeing correspondingly rotated whereby one of the ma trix retainingfingers will be moved by its respective cam projection into position toengage the foremost matrix in its corresponding channclto preventdelivery of such matrix while the other retainii'ig pawl will from theescapement pawl 7 so that this escapement pawl will reingage' theshoulder 25 with certainty after a matrix has been delivered from theother channel.

The actuating arm 23 for the reversing cam is, according to the presentinvention, actuated at appropriate intervals from the line deliverycarriage 26 when the line carriage begins to deliver the composed lineof matrices and spacers, the line carriage being provided for thispurpose with an.

operating projection 27 to cooperate with a latch 28, the latter beingturnable on a stationary pivot 29 and it has an operating shoulder 30"to coiiperate with an operating arm 31, the latter being also mountedto turn on the pivot 29, and the shoulder 30 is yieldably held inengagement with the arm 31 by a tension spring 32. A link 33 ispivotally connected to the arm 31, and the upper end of this linlt isoperatively connectcd to a lever 3a, the latter beingturn able on astationary pivot 35 and it has a slot 36 which operatively engages a pinor projection 37 on the ratchet-actuatingarm 23. A spring 38 returns thelink 33 and the connected parts to normal position after each actuationthereof by the line carriage,

lt'ach delivery movement of the line carriage 26 toward the left in Fig.2 causes the projection 27 thereon to engage the latch- ,28 and turn thelatter about its pivot 29, the

shoulder 30 on the latch bearing on the arm 31 and causing the latter tobe turned also about the pivot 29. In this manner, the bar 33 movesdownwardly and the slotted end.

of the lever moves upwardly carrying with. it the pin or projection 37on the actuating arm 23 and thereby causing the ratchet wheel 21 torotate one step, and owing to the operative relation between the cam andthe ratchet wheel, one of the. retainingpawls will permit delivery of amatrix from one magazine channel, and the other retaining pawl willprevent delivery of a matrix from its respective channel.

During the movement of the line carriage,

the operating projection 27 thereon will trip past the latch 28 owing tothe arcuate path of movement of the lower end of this latch, and whenthe line carriage returns to initial position or moves toward the rightin Fig. 2, the operating projection 27 will trip past the latch, asillustrated diagrammatically by the dotted lines in this figure, thistrip ping action being permitted owing to the pivotal relation betweenthe latch and the arm 31 and the yielding of the spring 32 whichconnects such parts. It is therefore obviousthat a suflicient supply ofmatrices is provided for by the plural number of magazine channels, andthat the matrices are delivered uniformly from the different channelsowing to the alternate action of the matrix retaining pawls. It is to beunderstood that the shaft 1-9 can be extended and provided withadditional cams and retaining pawls in order that matrices may be dearelivered alternately from additional double matrix channels of themagazine.

It is advantageous to govern the delivery of matrices from the differentmagazine channels from the line delivery carriage as the latter operatesto reverse thematrix delivery mechanism so as to draw the matrices fromthe alternate channels immediately after each line hasbeen composed andwhile such line is being delivered, a supply of the desired matricesbeing thereby insured at the commencement of the composition of eachline. 7 1 r I claim as my invention 1. In a machine of the linotypeclass, the combination \vitha magazine having a plurality of matrixcontaining channels, es-

'capement means operative to cause delivery of matrices from suchchannels, and a re ciprocatory line delivery carriage, of means forcausing delivery of matrices alternately from dillerent magazinechannels embodying a member located in the path of movement of the linedelivery carria e and operative by said carriage during the linedelivery movement thereof,

2, In a machine of the linotype class, the combination with a magazinehaving a plurality of matrix containing channels, escapement meansoperative to deliver matrices from such channels, and a reciprocatoryline delivery carriage, of means for causing delivery of matricesalternately from dili'erent magazine channels embodying a pivoted leverarranged in the path of movement of the line delivery carriage andactuated by said carriage when the latter moves in one direction andpermitting reverse reciprocation of said carriage without producingoperative movement of said lever.

3. In a machine of the linotype class, the combination with a magazinehaving a plurality oi? matrix containing channels, escapement meansoperative to cause delivery of matrices from said channels, and areciprocatory line delivery carriage carrying an actuating projection,of means for causing delivery of matricesalternately from said channelsembodying a lever pivoted on a fixed axis relatively to said carriageand having a portion arranged in the path of the actuating projection onthe carriage, said projection actuating said lever and disengagingtherefronrdnrmg movement of the line delivery carriage in one direction.

4. In a machine of the linotype class, the combination with a magazinehaving a plurality of matrix containing channels, escapement meansoperative to deliver matrices from said channels, and a reciprocatoryline delivery carriage having an actuating projection movable therewith,of means for causing delivery of matrices alternately from said,magazine channels embodying" a lever pivoted on a fixed axis andoperative in one direction by said projection and ans: toniaticallydisengaging therefrom when the" line delivery carriage moves in onedirection and movable idly in a reverse direction by said projectionduring a reverse movement of the'line delivery carriage.

In testimony whereof I have hereunto set my hand in presence of twosubscribing wit nesses.
